Title: Improvements in or relating to personal weighing machines
IPC: G01G19/46
Filed: 1935-05-20
Abstract: 439,670. Spring balances. ALTMANN, J., and ALTMANN, F., 24, Vinzenzgasse, and SCHON, A., 28, Pazmanitengasse, both in Vienna. May 20, 1935, Nos. 14690 and 14691. Convention dates, May 19, 1934 and Sept. 11, 1934. [Class 143] A personal spring weighing-means is provided with a suspended seat which is adjustable to different heights above the floor, in such a way that persons of different statures, when sitting upon the seat can touch the floor with their feet and thereby rapidly damp the oscillations of the balance. The balance is suspended by a hook from the door frame and the suspension means 1, Fig. 1, may be adjusted in length by a buckle 4 to bring the seat 10 to a convenient height for the user. The dial 5 or weight indicator is located at about the eye level of the seated person. For convenience of seating himself, the belt forming one side 3, Fig. 6, of the seat support may be unhooked from the spring. The indicator may consist of a spring drum 16, Fig. 9, rotatably mounted on an horizontal portion 14 of the spring. A cord 17 secured adjustably to the upper end of the spring rotates the drum when the spring elongates, and a fixed pointer 21 indicates the load. In a modified indicator instead of a dial, a graduated band 17, Fig. 11, readable against a transverse reading line is secured at one end to the upper portion 15 of the spring, and at the other end to an adjustable spring drum 36. To give a more open scale on the band 17 the movement of the band may be increased by passing it round a pulley on the portion 15 and securing the end to the lower part of the spring. Instead of employing a spring drum 36 a suspended weight may be used. In further modifications, two parallel weighing springs are used and the indicating band is arranged between the springs. The springs may support at their lower ends a stirrup 40, Fig. 17, from the ends 44 of which the seat is suspended. The indicating band 17 passes through a guide in the stirrup. The two weighing springs may be formed integral with one another. The Specification as open to inspection under Sect. 91 describes also a modification wherein the seat is replaced by a suspended device within which the person may stand. This subject-matter does not appear in the Specification as accepted.

Abstract: 676,698. Impedance networks. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 2, 1949 [Aug. 4, 1948], No. 14872/49. Class 40 (viii). A resonant circuit with variable tuning capacity is capacity - coupled to a utilization circuit and the coupling and tuning capacities are arranged to be varied together so that the former is increased when the resonant frequency of the circuit is decreased. As shown, the circuit comprises two cylinders 1 and 4 having gaps 6 and 11. The grid 21 of a valve 2 is capacitatively coupled thereto by connection to a strip 7 in the gap. Rotation of cylinder 4 as indicated by arrow 14 varies the resonance frequency of the structure and at the same time varies the capacity coupling through strip 7 in the desired sense. In a more elaborate construction the anode 16 of the valve has its simple connection 3 to the cylinder 1 replaced by a resistance connection in parallel with a capacity connection through a second strip in the gap 6. Further, cylinder 1 may have another slot crossed by an inductive loop to produce a variable inductance when cylinder 4 is moved. Finally, cylinder 4 may be replaced by a moving mass of material of high dielectric constant. A circuit of similar nature having lumped impedances is also described.

Title: Improvements in and relating to the mechanical treatment of tricalcic phosphates
IPC: C05B1/02
Filed: 1919-06-14
Abstract: Natural tricalcic phosphates are mechanically treated to obtain two fractions, one of rich granules containing a high percentage of phosphate, and the other of a mixture containing calcium carbonate and phosphate in so fine a state of division as to be assimilable by the roots of plants.  The nodules of natural phosphate are first broken down and then treated in a rotary disintegrator through which a blast of air is directed.  By this means, the granules of phosphate are freed from the carbonate dust which covers them and the mixture is carried away to chambers where the two fractions separate out according to density. Specification 122,897 is referred to.
